Using Virtual IPs in Networking
What is a virtual IP used for?
a) A virtual IP is a temporary IP address assigned to a device.
b) A virtual IP is used to represent multiple physical IP addresses.
c) A virtual IP is always static and never changes.
d) A virtual IP is a unique IP address for each virtual machine.
Final answer:
Answer:
A virtual IP is used to represent multiple physical IP addresses and is a unique IP address for each virtual machine.
In networking, a virtual IP address is used to provide failover and redundancy capabilities. A virtual IP is a method to make networked systems more robust and capable of handling incoming network traffic more flexibly, providing for high availability and scalability of IP-based services hosted on server clusters.
A virtual IP can be explained as an IP address that doesn't correspond to an actual physical network interface (like a network card). Instead, it provides a kind of abstraction layer that can be dynamically reassigned to any of the physical real IP addresses of the machine according to current requirements. In virtual machine environments, each VM will receive its own unique virtual IP.
This level of abstraction allows a virtual IP to represent multiple physical IP addresses while also providing a unique IP address for each virtual machine. This flexibility increases the resiliency and adaptability of networked systems.
